In a laboratory experiment, john uses a mesh to separate soil particles from water. which technique of separation is he using?

Hi there,

He is using filtration technique. It's a technique which is used for separation of solids and fluids by putting them through a medium which allow only fluid to pass through, leaving the solids (in this case the soil) alone. The fluid that passed is called the filtrate.

Hope this helps,
